RCT (n=47) - three short VR sessions helped autistic teens and adults respond more effectively in live police encounters, vs matched video
An RCT randomized 47 verbally fluent autistic participants (ages 12-60) to Floreo's VR Police Safety Module or BeSAFE The Movie video modeling: three 45-minute sessions each, with ~12 minutes of active VR practice per session. The VR group gave significantly more appropriate responses and showed calmer body language during live post-intervention interactions with real officers; the video-modeling group did not. Both groups reported greater knowledge and comfort with police interactions after training.
First scoping review of immersive VR in speech-language pathology maps two decades of research
A scoping review in AJSLP synthesized 11 peer-reviewed studies (2007-2025) using immersive VR with people who have communication differences. Across populations, immersive VR elicited communicative and emotional responses comparable to real-world contexts, with consistent presence and engagement findings. Sample sizes ranged from 3 to 36 participants, ages 9-81 years. The review describes the field as still early-stage and disproportionately focused on stuttering (5 of 11 studies).
Pilot of Immersive VoiceSpace VR (N=17, vocally healthy plus people with dysphonia) - participants scaled loudness and pitch across graded virtual restaurant conditions
A within-subjects pilot of Immersive VoiceSpace (IVS), a custom VR voice-training platform developed by the sole author. Seventeen adults (10 vocally healthy speakers and 7 people with dysphonia) completed a menu-ordering task in a virtual restaurant under four conditions - a baseline plus three graded IVS levels manipulating avatar distance, voice-activation thresholds, and walkaway timeouts. Sound pressure level and mean speaking f0 increased significantly across IVS levels in both groups; pitch flexibility was more constrained in the dysphonia group. Feasibility ratings were good overall (4.0/5), with comfort and safety excellent (4.5/5) and no cybersickness reported.
VR-based meditation reduced anxiety before voice therapy in a small exploratory RCT, with lower attrition in the VR arm
Twenty-six dysphonia patients with elevated state anxiety were randomized to a brief 10-12 minute meditation either with immersive VR (TRIPP app on Quest 2) or audio-only, delivered before each of four voice therapy sessions; 21 were analyzed. Both groups significantly reduced state anxiety with no Group x Time interaction (p=.207) - the modalities were comparable on the primary outcome.
Virtual audiences trigger real anxiety and comparable voice responses
Sixty university students gave presentations to a real audience, a virtual audience, and an empty virtual room. The virtual audience triggered anticipatory anxiety and heart rate increases similar to the real audience, and voice measures were largely equivalent across conditions.
Brief VR voice therapy with clinician feedback elicited teaching-style prosody in pre-professional teachers - but also significantly increased reported vocal discomfort
A single-session within-subjects pilot with 10 pre-professional teachers (9 analyzed). Both a teaching-style mock lesson and a clinician-controlled VR teaching intervention elicited teaching-style prosody vs a conversation control. CTT-style clinician feedback inside VR produced short-term modulations in SPL, fo, and Dt%. Critically, the VR condition also significantly increased self-reported vocal discomfort vs control (+20.5 VAS, p=.023) - a caveat that should travel with any clinical citation.
Pilot RCT in youth who stutter: real-time photorealistic-avatar VR is well-accepted and elicits arousal, but one session did not outperform SLP role-play
A pilot RCT randomized 12 children and adolescents who stutter (ages 9-18) to one of two training conditions before facing an unknown actor-teacher: a conversation with a photorealistic virtual teacher in VR controlled live by their own SLP via facial motion capture (n=6), or face-to-face SLP role-play (n=6). The VR system was well-accepted (high presence, low cybersickness). Skin conductance was elevated from baseline in the VR group; SLP role-play raised self-reported anxiety more. A single session did not outperform role-play on self-efficacy or post-task in vivo anxiety.
Virtual room size and listener distance influence how people use their voice
Using the Rooms module of Therapy withVR, this study found that speaker-to-listener distance in virtual environments significantly influenced vocal intensity and mean fundamental frequency, with trained singers showing more systematic vocal adjustments across distance conditions than untrained speakers.
100-participant RCT of commercial VR cognitive training (Beat Saber) in chronic TBI: null primary outcome on sustained attention, secondary gains in processing speed, executive function, and quality of life
100-participant parallel-group RCT comparing unsupervised home-based VR cognitive training (Beat Saber on Quest 2, 30 min/day, 5 days/week, 5 weeks) against a nonspecific counseling-plus-booklet control in chronic complicated mild-to-severe TBI. The pre-registered primary outcome of sustained attention (CoV on CPT-3) was null at every timepoint. Secondary outcomes favored VR: a speed-accuracy tradeoff (longer reaction times, fewer errors), better self-reported executive function (BRIEF-A), and better quality of life (QOLIBRI), with a more efficient inverse-efficiency score at 16-week follow-up.

Structured Turkish review of VR, mobile apps, telerehab, and AI for stuttering: VR has the strongest evidence of the four, but research remains preliminary
A Turkish-language structured review (also published in English) examining four technology domains for stuttering rehabilitation: virtual reality, mobile applications, telerehabilitation, and artificial intelligence. A six-database literature search (2000-2024) identified 55 studies; 13 met inclusion criteria; six AI-related patents on Google Patents were also surveyed. VR had the strongest evidence base of the four domains, but the authors stop short of clinical recommendations.
A tutorial overview of how immersive VR might support people with neurogenic communication differences
An ASHA tutorial reviewing immersive VR for speech-language rehabilitation of adults with neurogenic communication disorders. The author's overall conclusion is that there is currently insufficient evidence that immersive VR directly benefits communication outcomes in this population. withVR is named once as one example of emerging applications 'being developed by and for persons with communication differences'; the paper does not use, test, or evaluate withVR.
Qualitative study of patient and therapist experiences with immersive VR-assisted therapy for distressing auditory hallucinations (voices) in psychosis - from the Danish Challenge Trial multi-site collaboration
A qualitative study of participants' and therapists' experiences with Immersive VR-Assisted Therapy for distressing voices in psychosis, conducted within the Challenge Trial. Multi-site Danish + Australian + UK collaboration (Aalborg University Hospital, Copenhagen Mental Health Services, Orygen Melbourne, Swinburne University, Institute of Psychiatry London). Examines how patients with psychotic disorders experiencing distressing auditory hallucinations relate to immersive VR therapy and how therapists deliver it. Complements Pot-Kolder 2018 (VR-CBT for paranoid ideation in psychosis) with a focused qualitative lens on the distressing-voices subtype of psychosis.
Systematic review (2025) of VR + AR + MR training for autism social skills: 7 studies, 417 individuals - broader scope than VR-only autism reviews, occupational-therapy lens
A systematic review published in the Hong Kong Journal of Occupational Therapy synthesizing VR + augmented reality + mixed reality (VAMR) training for social skills in autistic individuals. Literature search across MEDLINE, EMBASE, ERIC, Web of Science. Seven studies were included totaling 417 autistic individuals. All studies were judged to have unclear risk of bias regarding the randomization process. The review's contribution is breadth - including AR and MR alongside VR - and the occupational-therapy framing relevant for OTs and allied clinicians working with autistic individuals.
Three and a half decades of SLT economic evaluation - still a small, fragmented, poorly interconnected literature
A scoping review of 52 economic evaluations of speech and language therapy interventions published between 1988 and 2023. The field is growing (3-5 publications a year since 2019) but remains small, methodologically heterogeneous, and poorly interconnected - only 18 of 43 studies cited another included study. No economic evaluations of VR-based SLT interventions were identified.
VR-based speaking practice increases willingness to communicate in gender-affirming voice training
The first RCT using Therapy withVR for gender-affirming voice training found that practicing in virtual speaking situations led to broader gains in willingness to communicate with strangers compared to traditional in-person role-play.
Mixed-methods study (n=10) of an Immersive VR Systems platform for autism communication and cultural-understanding skills in Thai school settings: quantitative SCQ scores non-significant, qualitative parent and therapist feedback positive
A mixed-methods study from Chiang Mai University, Thailand, examining the design and development of an Immersive Virtual Reality Systems (IVRS) platform for autistic children in Thailand. Population: 10 autistic children. Setting: home-based / school-based use without direct therapist involvement. Quantitative measure: Social Communication Questionnaire (SCQ). Qualitative data: semi-structured interviews with parents and therapists. Quantitative SCQ scores did NOT show statistically significant improvements (likely under-powered at n=10), but qualitative feedback highlighted the platform's effectiveness in enhancing social interaction and communication skills. Useful as a supplementary tool for therapists.
A seven-year interdisciplinary case study of co-designing an immersive VR kitchen environment for speech-language pathology rehabilitation and aging-in-place
A multi-phase, multi-disciplinary case study describing the seven-year design, development, and feasibility testing of an immersive VR kitchen environment for speech-language pathology rehabilitation and aging-in-place practice. The collaboration brought together speech-language pathologists, interior designers (aging-in-place specialists), VR programrs, and technology consultants. The paper describes the design-thinking methodology, phase-by-phase development, HIPAA-aware infrastructure choices, and lessons for interdisciplinary VR co-development - rather than reporting clinical outcome data on patients.
Voice SLPs and their patients evaluate a fully immersive VR prototype for the transfer phase of voice therapy
A user-centered qualitative evaluation of ProVoiceVR - a fully immersive head-mounted VR prototype - found that both voice speech-language pathologists and patients with voice disorders saw clear potential for using VR to help patients practice and consolidate voice techniques in realistic everyday speaking situations.
Most SLTs know VR exists - almost none have used it with autistic children - and what would change that is very specific
A UK and Ireland survey of 53 speech and language therapists working with autistic children found that 92% were aware of VR but had not used it clinically. Only one SLT (1.8%) had used it with an autistic child. The barriers cited were specific and addressable: autism-specific VR knowledge, workplace support, training, and clear clinical guidelines. 80% said they would try VR with proper training and evidence.
First scoping review (2025) of digital health technology for dysphagia rehabilitation - covering VR, AR, video games, telehealth, AI-based systems, and mobile apps for swallowing therapy
A scoping review published in Journal of Evidence-Based Medicine synthesizing the digital technology landscape for dysphagia (swallowing) rehabilitation. Searched Medline Complete, Embase, CINAHL, Scopus, and grey literature for articles published January 2000-mid-2024. Covers personalized exercise platforms, remote monitoring, real-time feedback systems, VR, video games, AI-based interventions, and mobile applications across the dysphagia care continuum. The first major review for our Hub's swallowing topic, which previously had only one study.
Systematic review (JMIR 2025) of VR technology interventions for social skills in autistic children and adolescents - distinguishing immersive from non-immersive VR and flagging implementation considerations
A systematic review published in the Journal of Medical Internet Research synthesizing the evidence on VR technology interventions for improving social skills in autistic children and adolescents. Key distinctions emphasized: immersive VR interventions are more suitable for complex skill development, while non-immersive VR (lower cost, greater flexibility) holds potential for specific contexts. The review also flags implementation side effects including dizziness, eye fatigue, and sensory overload - particularly in immersive settings - which should be addressed in intervention design. Identifies a research gap: limited large multicenter RCTs and small per-study sample sizes.
Systematic review of VR interventions for social skills in autistic children, published in Journal of Autism and Developmental Disorders (2025) - examining how VR can supplement traditional autism interventions
A systematic review of VR interventions designed to support social skills development in autistic children, published 2025 in the Journal of Autism and Developmental Disorders (Springer). Examines the rationale (the difficulty of replicating scenarios like emergencies, crowded public transportation, restaurants in real-world settings is cost-prohibitive), the available VR intervention designs across the autism+VR literature, and what the evidence base shows about effectiveness. Conducted by Altın, Boşnak, and Turhan (Turkish research team).
Immersive VR helps healthy adults learn rare words faster than a tablet method, but does not outperform a structured tablet method for aphasia anomia rehabilitation
Two within-subject experiments using a virtual marketplace iVR application against a matched-exposure tablet (digital static learning, DSL) method. In 32 neurotypical French adults learning rare French words, iVR significantly outperformed DSL by Day 3 (z = 4.556, p < .0001). In 16 people with mild-to-moderate post-stroke aphasia learning frequent French words in a crossover design, both methods produced significant learning gains across Day 1, 5, 12, and 19 (p < .001), but iVR was NOT significantly better than DSL on accuracy (estimate 0.025, p = .704).
Engineering + user-reception study (Computers & Graphics 2025) of a speech-controlled VR system for voice and public-speaking training: extracts pitch / timbre / speech rate from 529 utterances by 15 students for real-time virtual character response
An engineering and user-reception study published in Computers & Graphics special section on XRIOS 2024. Polish-British collaboration (AGH Krakow, SWPS Warsaw, Polish Academy of Science, Kielce University of Technology, University of Cambridge). The system is built on a speech recordings corpus of 529 utterances during presentations by 15 students. Voice parameters extracted: pitch, timbre, speech rate. Six expert annotators evaluated stress levels per presentation. The multi-parameter analysis selects features for real-time animation of virtual characters responding dynamically to speech changes. The contribution is design and user-reception evaluation rather than clinical efficacy.

External attentional focus in VR promotes more flexible speech movement in adults who stutter
Using Research withVR, this study found that directing attention outward (toward a moving VR target) rather than inward (toward articulators) reduced articulatory rigidity and increased speech rate in adults who stutter.
VR for speech therapy with children with cerebral palsy is feasible at home - with kids rating it higher than clinicians do
This pilot feasibility study tested the VRRS (Khymeia) system for speech therapy assessment with 28 children with cerebral palsy at IRCCS Stella Maris Foundation (Pisa, Italy), and followed three children with unilateral CP through a home-based tele-rehabilitation program. VRRS is a non-immersive 2D touch-screen platform (the same system used in Cappadona 2023), not a head-mounted VR system. Both assessment and home delivery worked. Children consistently rated the system higher than clinicians on usability and acceptability.
Qualitative feasibility study (JADD 2024): focus groups with 8 autistic adolescents (ages 12-17) + 5 parents on VR-delivered social skills programs - 7 primary themes identified through open thematic coding
A qualitative study published in Journal of Autism and Developmental Disorders exploring the feasibility of VR-delivered social skills programs for autistic youth. Eight autistic adolescents (ages 12-17) and five parents participated across five focus groups, with semi-structured interview format. Open thematic analysis with inductive coding produced seven primary themes covering adolescent and parent perceptions of social skills development needs, attitudes toward VR-delivered interventions, and concerns/desires for clinical implementation. Critical adolescent-voice work for the autism+VR field.
At-home VR speaking practice reduces stuttering and anxiety
Five adolescents and young adults who stutter used commercial VR headsets at home for one week, completing progressively challenging speaking scenarios. Stuttering frequency dropped nearly in half and heart rate decreased significantly.

Single-group pre-post pilot study of immersive VR 'outworld' experiences for 13 in-patients with dementia: feasible, well-tolerated, and qualitatively engaging
A single-group pre-post pilot study of immersive virtual reality experiences delivered to 13 hospital in-patients with dementia (mean age 73.2, range not reported; 13 women in the Nudelman scoping review listing). Patients used an HTC VIVE Pro Eye HMD to access curated 'outworld' VR environments (places they could no longer visit in person). Mixed-methods evaluation combined pre-post quantitative measures with qualitative interviews. The VR experience was well-tolerated and produced positive engagement, though the small single-group design without a control limits causal inference about therapeutic benefit.
Protocol for an RCT testing video-game based swallowing training for post-stroke dysphagia
This paper describes the protocol for a planned randomized controlled trial that will test whether a video-game based swallowing training program driven by surface electromyography (sEMG) biofeedback is more effective than conventional swallowing training for adults with post-stroke dysphagia. No results are available yet - this is the study design and methodology plan, registered on ClinicalTrials.gov as NCT05978700.
Pilot RCT in 32 children with developmental language disorder (mean age 4.8y): broader language gains with VR-supported therapy and 100% retention over six months
32 children (mean age 4.8 years) with developmental language disorder were randomized to VR-supported speech intervention or standard care for six months (2 × 1-hour sessions per week). The VR system used was VRRS - a non-immersive 2D touch-screen platform, not a head-mounted display. The VR group showed within-group improvements across more language domains than the control group. Retention was 100% - no dropouts - a feasibility signal that matters in this age group.
Within-subjects study in 31 vocally healthy adults: auditory, visual, and audiovisual room cues in immersive VR all measurably change self-perceived vocal loudness, effort, comfort, and acoustic output
Thirty-one vocally healthy men and women were tested under 18 sensory-input conditions in immersive virtual reality - two auditory rooms with different reverberation times, two visual rooms with different volumes, and audiovisual combinations - each with and without background noise. Speakers performed counting, sustained vowels, an all-voiced CAPE-V sentence, and a Rainbow Passage sentence. Self-perceived vocal loudness and effort INCREASED, and self-perceived vocal comfort DECREASED, as room volume, speaker-to-listener distance, audiovisual richness, and background noise increased. Sound pressure level (SPL) and spectral moments (mean, SD, skewness, kurtosis) showed concomitant changes. Visual and audiovisual input - not just auditory - measurably shaped voice production.
VR-based tasks reveal distinct cognitive profiles in stuttering and ADHD
This doctoral thesis (supervised by Prof Peter Howell and Dr Daniela Romano at UCL) used VR-based tasks with EEG and eye tracking to compare attention and executive function across adults who stutter, adults with ADHD, and neurotypical controls. The cognitive profiles were found to be distinct, supporting the paper's central argument that comorbidity between people who stutter and people with ADHD is overstated. Network Models were used as the central analytic method.
Case series (n=3) - at-home VR classroom practice was feasible and lowered heart rate in young people who stutter
Three young people who stutter (ages 9-12) used a portable VR headset at home for two weeks, practicing speaking in a virtual classroom. Two showed reduced stuttering afterward, all showed decreased heart rate, and all reported the experience was fun, realistic, and confidence-building.
VR public speaking tool tracks stress and emotion in real time
Researchers developed 'Speak in Public,' combining VR scenarios with wearable biosensors and speech emotion recognition for people who stutter. Testing with five young people showed every stuttering moment coincided with biosensor-identified stress, and emotion profiles varied meaningfully across scenarios.
Speech-language pathologists see potential in VR for TBI cognitive-communication work - if training, guidelines, and evidence catch up
A qualitative study of 14 speech-language pathologists and 3 VR researchers explored attitudes toward using VR with adults who have cognitive-communication difficulties after traumatic brain injury. Participants were broadly positive about VR as a way to rehearse real-world communication, but raised concrete concerns about safety, access, cost, and the absence of clinical guidelines. The study surfaces what clinicians need before VR can move from interesting to routine.
Pilot RCT of self-guided smartphone-based VR exposure therapy for social anxiety in people who stutter (null result on primary outcomes)
A pilot RCT (n=25 adults who stutter) of three weekly sessions of self-guided smartphone-based VR exposure therapy versus waitlist. Primary outcomes - social anxiety, fear of negative evaluation, stuttering-related thoughts, and stuttering characteristics - did not differ significantly between groups pre to post. The authors conclude that the current self-guided protocol may not be effective on its own, though scores trended down in both arms.
Scenari-Aid DVD simulation tool well-received by adults who stutter
Thirty-seven adults who stutter used the Scenari-Aid DVD social simulation tool with 25 pre-recorded video scenarios across 7 scenario categories and then completed a survey. Participants overwhelmingly endorsed the tool, with 97-100% positive agreement on anxiety items, 84-97% on fluency items, and 76-97% on therapy/fluency technique value items.
First systematic review of VR in aphasia rehabilitation: a comprehensive synthesis of the evidence base from City University of London / Center for Excellence in Aphasia Research
The first systematic review synthesizing the evidence base for using virtual reality in the rehabilitation of aphasia. Conducted by the Devane / Marshall / Hilari City University of London group. Published in Disability and Rehabilitation, the established Taylor & Francis peer-reviewed rehabilitation journal. The review covers types of VR systems used, target rehabilitation goals (anomia, conversation, social participation, attention), outcome measures, and effectiveness across the included studies. With 26+ citations and over 11,000 article views by 2025, this is the foundational synthesis reference for VR-in-aphasia rehabilitation work.

Narrative review of 5 VR-stuttering studies - VR matches live-audience conditions and repeated sessions reduce anxiety
The first VR-stuttering paper in Croatian academic literature. This narrative review synthesized five empirical studies examining VR with adults who stutter. Consistent evidence showed that VR environments produce communication experiences comparable to real-world settings and that repeated VR speaking sessions reduce anxiety. Authors are affiliated with DV Latica Zadar and the University of Zagreb Faculty of Education and Rehabilitation Sciences.
Scoping review of VR exposure therapy for social anxiety and how it could be adapted for stuttering
A scoping review of twelve studies of VR exposure therapy (VRET) for adults with social anxiety, structured to identify design variables (sessions, dose, hardware, environments, audience configurations) relevant to adapting VRET for people who stutter. The review formulates testable design hypotheses rather than empirical conclusions for the stuttering question.
What the research says about VR and AR for people with communication differences across the lifespan
A systematic review of VR and AR applications for children, adolescents, and adults with communication differences found growing evidence of feasibility and positive outcomes, while highlighting the need for more rigorous research designs and larger studies.
Mixed-methods study of 15 speech-language pathologists' acceptance, barriers, and enablers of using an immersive VR kitchen environment for communication rehabilitation
Fifteen speech-language pathologists participated in everyday-life communication activities inside an immersive VR kitchen environment, then completed system-usability and motion-sickness surveys plus semi-structured interviews. System usability was average; motion sickness was low. The qualitative analysis identified five themes - attitude toward VR in communication rehabilitation, perceived usefulness, perceived ease of use, intention to use, and clinical adoption barriers and enablers. SLPs were broadly positive about VR's potential as an ecologically valid communication-rehab tool while identifying real-world implementation barriers.

Three-participant feasibility case study of an Arabic-language VR public-speaking system with an automated stuttering-event detector
A three-participant feasibility case study (two female, one male, ages 30-34) of an Arabic-language VR public-speaking system on a Samsung Gear VR + S6 phone, paired with an automated stuttering-event detector. Each participant completed one session reading from a virtual podium facing a virtual audience. Setup time 2-3 minutes; the automated detector correlated R=0.95 with manual clinician counts on the same audio.
Pilot RCT (n=44) of brief self-guided virtual reality exposure therapy for social anxiety disorder: moderate-to-large effects on SAD severity, job interview fear, and trait worry, maintained at 3 and 6 months
Forty-four community-dwelling or undergraduate adults diagnosed with social anxiety disorder (SAD) using the Mini International Neuropsychiatric Interview were randomly assigned to a self-directed VR exposure intervention (designed to last four sessions or more; n=26) or a waitlist control (n=18). Outcomes measured at baseline, post-treatment, 3-month follow-up, and 6-month follow-up. VR exposure produced moderate-to-large reductions in SAD symptom severity, job interview fear, and trait worry (Hedges' g = 0.54 to 1.11). Although between-group differences in depression were not significant, the VR arm reduced depression while waitlist did not. Gains were maintained at 3- and 6-month follow-up. Self-reported presence increased during treatment (g = 0.36 to 0.45); cybersickness decreased (g = 0.43).
Three-arm RCT (n=51) of stand-alone 360° video VR exposure therapy for public speaking anxiety: both audience-content and empty-room content produced significant pre-to-post reductions (partial η² up to .90) versus no-treatment control
Fifty-one participants with high public speaking anxiety were randomly allocated to one of three conditions: 360° video VRET incorporating audience stimuli (n=17), 360° video VRET incorporating empty-room stimuli (n=16), or no-treatment control (n=18). Outcomes measured at five timepoints. Mixed-ANOVA revealed a significant time × intervention-group interaction for PSA, social anxiety, and fear of negative evaluation (FNE). Both 360° VRET groups showed large pre-to-post reductions; for PSA, partial η² = .90 (audience) and .71 (empty room). Active intervention participants showed continued significant improvement out to 10-week follow-up. The study also addresses whether 360° video content (audience vs empty room) affects VRET outcomes - both worked.
In ten children and adolescents who stutter, virtual classrooms produced anxiety and rated stuttering severity comparable to a live audience
Ten school-age children and adolescents who stutter spoke under three conditions: an empty virtual apartment, a virtual classroom (neutral and challenging variants), and a small live audience. Self-reported anxiety and clinician-rated stuttering severity in the virtual classroom did not differ significantly from the live audience, and virtual-classroom anxiety correlated strongly with live-audience anxiety (Spearman rho = 0.92, p < .001).
Stuttering adaptation is stronger in VR than in real-world settings
This study examined whether people who stutter show the expected decline in stuttering across repeated readings in VR compared to real-world settings. Twenty-four adults completed tasks in both environments, and the adaptation effect was actually stronger in VR.
A VR classroom successfully brings out how teachers really use their voice when teaching
A THREE-condition experiment: teachers delivered lessons in a real classroom (in vivo), in a virtual classroom (in virtuo), and in a free speech control situation. Voice parameters (intensity, pitch, intonation) and temporal measures (pause duration) were compared across all three. The virtual classroom successfully elicited teaching-voice characteristics matching in-vivo teaching, providing validation that VR can substitute for real classrooms in voice research and support.

PROSPERO-registered systematic review + meta-analysis (22 studies, n=703) in Psychological Medicine: VRET for social anxiety disorder is efficacious with durable effects, and treatment-discontinuation rates are comparable to in-vivo exposure
A PROSPERO-registered (CRD42019121097) systematic review and meta-analysis of VRET for social anxiety disorder, published in Psychological Medicine. Inclusion criteria: SAD or related phobias; at least three VRET sessions; minimum 10 participants. 22 studies met criteria (total n=703). Primary outcome: social anxiety evaluation score change synthesized with Hedges' g random-effects modeling. Secondary outcome: risk ratio for treatment discontinuation. The review evaluates VRET's magnitude of efficacy, duration of efficacy, and dropout rates against in-vivo exposure and against passive controls.
A feasibility RCT of group social support in a virtual world for aphasia - feasibility met, no significant quantitative outcomes
A waitlist randomized feasibility RCT with 34 recruited (29 completed, 85.3%). People with aphasia attended 14 EVA Park social group sessions over 6 months. Feasibility targets were met: recruitment achieved, 85.3% completion, all groups ran as planned. However, no significant change was observed on any quantitative outcome measure (wellbeing, communication, social connectedness, quality of life). Qualitative reports were positive. Trial registered NCT03115268.
VR self-modeling improved conversational stuttering but had limited effects on prompted speech and anxiety
Three adults who stutter viewed edited 360-degree VR footage of themselves speaking fluently. All showed clinically meaningful reductions in conversational (unprompted) stuttering severity. However, effects on prompted speech were variable and limited treatment effects were found on anxiety data - with one participant's anxiety actually increasing. Data collection took place during the COVID-19 pandemic and period of racial unrest, which the author identifies as a confounding factor.
VR conversational practice helps people with aphasia communicate more effectively
A pilot RCT with 36 people with chronic aphasia comparing semi-immersive VR conversational practice (NeuroVR 2.0 on a 50-inch curved screen - not a headset) to conventional therapy over 6 months. No significant between-group differences were found on any measure. Within-group analysis showed the VR group improved on more domains, and only the VR group improved on self-esteem and emotional/mood state.
Mixed-methods study of 31 autistic children (ages 6-16) using VR head-mounted displays in schools - the high-fidelity HTC Vive was preferred, HMDs were reported as enjoyable, comfortable, easy to use, and useful for relaxation + pre-visit familiarization + school learning
A mixed-methods study placing 31 autistic children aged 6-16 at the center of a school-based investigation of VR head-mounted displays. Three research questions: which HMD do autistic children prefer, how do they experience HMDs physically and emotionally, and what would they want to use VR for in school? The high-end HTC Vive was preferred over lower-fidelity HMDs. Children reported VR as enjoyable, physically and visually comfortable, easy to use, exciting, and reusable. Identified uses: relaxation / feeling calm, virtual pre-visit to anxiety-inducing locations before real-world visit, learning opportunities in school.

Non-randomized feasibility and pilot study of one-session 90-minute VRET for 27 Norwegian adolescents (ages 13-16) with public speaking anxiety: large effect (Cohen's d = 1.53) maintained at 3-month follow-up with low-cost consumer VR hardware
Twenty-seven Norwegian adolescents aged 13-16 with public speaking anxiety received a one-session (90 minutes) VR exposure therapy intervention using a low-cost consumer head-mounted display with custom-built VR stimuli depicting a cultural and age-appropriate classroom and audience. Pre/post and follow-up self-report measures plus heart-rate recording during the session. Linear mixed effects modeling showed a LARGE pre-to-post effect (Cohen's d = 1.53) on PSA symptoms, maintained at 1- and 3-month follow-up. Heart rate increased modestly during exposure tasks. Feasibility improvements were iterated during the trial based on adolescent feedback.
PRISMA systematic review + meta-analysis of RCTs comparing VRET to in-vivo exposure in agoraphobia, specific phobia, and social phobia - with equivalent exposure dose in both arms
A pre-registered, PRISMA-compliant systematic review and quantitative meta-analysis of randomized controlled trials specifically comparing VR exposure therapy (VRET) to gold-standard in-vivo exposure for agoraphobia, specific phobia, and social phobia - with the critical inclusion criterion that the AMOUNT of exposure be equivalent in both arms. By controlling for exposure dose, the authors directly test whether the delivery modality (VR vs in-vivo) itself drives any outcome difference. The review covers literature through June 2019. Hedges' g effect-size synthesis is performed across the phobia disorders, with subgroup analysis by disorder.
An interactive gaming system helps people with aphasia improve word-finding and verbal fluency
An RCT found that people with aphasia who used an interactive gaming system showed improvements in naming ability and verbal fluency compared to those receiving conventional support, suggesting game-based approaches can complement language recovery.
Major meta-analysis (2019) of 30 randomized controlled trials of virtual reality exposure therapy for anxiety and related disorders (n=1,057): large effect vs waitlist (g=0.90) and equivalent to in-vivo exposure
An updated meta-analysis extending Powers & Emmelkamp 2008 to 30 randomized controlled trials (n=1,057 participants) of virtual reality exposure therapy (VRET) for anxiety and related disorders. Coverage: 14 trials of specific phobias, 8 of social anxiety disorder or performance anxiety, 5 of PTSD, and 3 of panic disorder. Random-effects analysis gave a large effect size for VRET vs waitlist (Hedges' g = 0.90) and a medium-to-large effect size for VRET vs psychotherapy comparator conditions. Confirms that VRET is a clinically effective option across the anxiety-disorder spectrum, with social anxiety and performance anxiety as the subset most relevant to communication work.
First RCT (n=25+25) showing that consumer VR hardware and software can deliver effective one-session VRET for public speaking anxiety - both therapist-led (d=1.67) and self-led at home (d=1.35), with gains maintained at 6 and 12 months
Twenty-five participants were randomised to one-session therapist-led VR exposure therapy for public speaking anxiety using consumer VR hardware and software, followed by a 4-week internet-administered VR-to-in-vivo transition program; another 25 served as a waiting-list. Therapist-led VRET produced a very large effect on self-reported PSA (within Cohen's d = 1.67). The waiting-list then received internet-administered, SELF-LED VRET at home, followed by the same transition program - producing a large effect (d = 1.35). Results were maintained or improved at 6-month and 12-month follow-ups. This is the first published RCT demonstrating that off-the-shelf consumer VR hardware and software can deliver effective PSA exposure therapy in both clinician-supervised and home-based formats.

VR social interaction practice is acceptable and feasible for people with schizophrenia
A feasibility study finding that a VR-based social skills program (MASI-VR) was well-received and practical for adults with schizophrenia spectrum experiences, with participants showing improvements in social functioning.
A map of every reason VR succeeds or stalls in rehabilitation clinics
A scoping review of barriers, facilitators, and knowledge-translation interventions for VR and active-video-game (VR/AVG) implementation in rehabilitation. Used the Theoretical Domains Framework to structure findings across all but 1 of 14 TDF domains; 24 articles were included, ~75% from neurologic rehabilitation (stroke, CP, ABI). A consistent awareness-to-use gap was documented: many clinicians know of VR/AVG but few use it routinely. The review's contribution is procedural and implementation-focused - it does NOT review specific VR therapy efficacy.
Two meta-analyzes of VRET for social anxiety: (1) 6 studies (n=233) confirmed VRET more effective than waitlist; (2) 7 studies (n=340) showed essentially no difference between VRET and in-vivo/imaginal exposure - supporting VRET as a non-inferior alternative to standard treatment
Two complementary meta-analyzes of VRET for social anxiety published in Behavior Change. The first compared VRET to waitlist control across 6 studies (n=233), showing a significant overall effect favoring VRET - confirming VRET reduces social anxiety better than no treatment. The second compared VRET to the standard treatment (in-vivo or imaginal exposure) across 7 studies (n=340), showing essentially no difference in effect sizes between VRET and in-vivo/imaginal exposure - supporting VRET as a non-inferior alternative. Together, the two meta-analyzes establish VRET as both effective in absolute terms AND clinically equivalent to the gold-standard exposure modality.
Fully automated VR therapy delivered by a virtual coach significantly reduced fear of heights
In a 100-person single-blind RCT, a fully automated VR program with a virtual therapist coach produced large reductions in fear of heights - achieving outcomes comparable to therapist-delivered care without requiring a clinician in the room.
Children with speech sound disorders preferred Apraxia World over traditional practice - a single-session comparison
A single-session, within-subjects study comparing two delivery conditions for Apraxia World - a tablet-based speech therapy game for children with speech sound disorders. The study assessed engagement and preferences across 21 children (14 with speech sound disorders, 7 typically developing), finding that the majority found the game enjoyable. The study is a user-experience and preference evaluation, not an efficacy trial.
Single-blind RCT (n=116) in The Lancet Psychiatry: VR-based CBT for paranoid ideation and social avoidance in psychotic disorders - VR-CBT did not increase social participation but DID reduce paranoid ideation, anxiety, and momentary social threat versus treatment-as-usual waiting-list control
A multi-center single-blind RCT at seven Dutch mental health centers. 116 outpatients aged 18-65 with DSM-IV psychotic disorders and paranoid ideation in the past month were randomized (1:1) to VR-based cognitive behavioral therapy (VR-CBT; 16 individual 1-hour sessions added to treatment-as-usual) OR waiting-list control (treatment-as-usual only). Assessments at baseline, post-treatment (3 months), and 6-month follow-up. Primary outcome: social participation (time spent with others, momentary paranoia, perceived social threat, momentary anxiety). Intention-to-treat analysis. VR-CBT did NOT significantly increase social participation, but DID reduce paranoid ideation, anxiety, and momentary social threat - establishing VR-CBT as a credible adjunct for paranoid symptoms in psychosis.
VR helped autistic children improve emotion expression and social reciprocity - but not emotion recognition or adaptive skills
A quasi-experimental study (72 analyzed from 94 enrolled) at three Hong Kong universities tested a half-CAVE projection VR program for autistic children aged 7-10. Primary outcomes - emotion expression/regulation and social-emotional reciprocity - showed significant improvement. Secondary outcomes - emotion recognition and adaptive skills - did NOT. The study used a half-CAVE system (4-sided projection screens with non-intrusive motion tracking), not a head-mounted display.

Umbrella review: clinical VR has matured into a viable tool, with caveats clinicians should know
An umbrella review by two senior figures in clinical VR examined the breadth of evidence across psychological and neurocognitive applications, concluding that VR is ready for routine clinical use in many contexts while flagging implementation challenges that practitioners should plan for.
Eye-tracking VR helps people who stutter improve gaze during conversation
This thesis integrated eye tracking into a VR exposure system to objectively measure gaze behaviors of people who stutter. Across three sessions, participants showed significant reductions in prolonged eye closures and a substantial increase in time spent looking at the avatar's face.
Harvard Review of Psychiatry narrative review of virtual reality in the treatment of anxiety and other psychiatric disorders - historical development, empirical evidence, benefits, and integration recommendations
A systematic literature review of VR-based treatment for anxiety disorders and other psychiatric conditions, published in the Harvard Review of Psychiatry. Covers the history of VR-based clinical technology, an overview of the empirical evidence (particularly exposure-based intervention for anxiety disorders), the benefits of using VR for psychiatric research and treatment, recommendations for incorporating VR into psychiatric care, and future directions. Authored by the Emory group (Rothbaum's lab), this is the authoritative narrative review of clinical VR for the 2017 era - frequently cited as the canonical reference for clinicians and trainees entering VRET practice.
Pre-registered three-arm RCT: CBT with VR exposure was superior to in-vivo exposure on the primary social-anxiety outcome - and more practical for therapists
A pre-registered three-arm RCT randomized 59 adults with DSM-5 social anxiety disorder to 14 weekly sessions of CBT with VR exposure (n=17), CBT with in-vivo exposure (n=22), or waitlist (n=20). The pre-specified superiority hypothesis was confirmed: VR exposure was significantly more effective than in-vivo exposure on the LSAS-SR primary outcome at post-treatment and at 6-month follow-up, and significantly less cumbersome for therapists (SWEAT: 15.24 vs 24.46). Reliable change: 76.5% VR, 68.3% in vivo, 30.0% waitlist.
First long-term (4-6 year) follow-up of VR exposure therapy and exposure group therapy for social anxiety disorder: durable gains, with 54% no longer meeting diagnostic criteria
Twenty-eight participants from the Anderson et al. 2013 RCT of VR exposure therapy (VRET) vs exposure group therapy for DSM-diagnosed social anxiety disorder were re-assessed a mean of 6 years (range 4-6) after treatment completion. Self-report measures, behavioral speech tasks, and diagnostic interviews all showed statistically significant improvement from pre-treatment to long-term follow-up. The majority (54%) no longer met diagnostic criteria for SAD; 68% rated themselves 'very much' or 'much' improved. With one exception, there were no differences between VRET and exposure group therapy at follow-up - both produce durable long-term benefits, consistent with the broader CBT-for-SAD evidence base.

VR audiences raise subjective distress but not physiological arousal or stuttering frequency in adult males who stutter
Ten adult males who stutter delivered impromptu speeches in a virtual audience and an empty virtual room. Subjective distress (SUDS) was significantly higher in the audience condition - but heart rate, skin conductance, and stuttering frequency did NOT differ between conditions, producing a dissociation between subjective and objective markers of distress in this VR setting.
Feasibility study (n=41 adolescents ages 13-18) showing that VR environments differentiate socially reactive from neutral scenarios AND distinguish youth with social anxiety disorder from non-anxious peers via SUDS during exposure
Forty-one adolescents aged 13-18 (20 with social anxiety disorder by LSAS-CA cutoff 29.5; 21 non-anxious) were exposed to four VR environments: a party scenario, a public speaking scenario, and two neutral scenarios. All participants reported significantly higher Subjective Units of Distress Scale (SUDS) ratings during party and public speaking scenarios versus neutral environments - establishing the system's discriminant validity. Critically, youth with SAD reported significantly higher SUDS in the social environments than non-anxious peers - establishing known-groups validity. Adolescents demonstrated acceptable levels of presence and immersion. The study supports VR exposure as feasible for adolescent SAD.
Bachelor's-dissertation pilot of an early Samsung Gear VR public-speaking prototype with 6 adults who stutter - mixed anxiety results across participants
A bachelor's-dissertation conference paper testing a custom Samsung Gear VR public-speaking app with 6 adults who stutter (4 returning for Session 2). Three animated audience characters in a virtual lecture hall; anxiety captured on a 1-5 self-report scale only. Results were mixed across participants - some decreased, some unchanged, some increased anxiety. Body temperature and EDA rose during exposure. Chard & van Zalk's 2022 scoping review explicitly excluded this paper for the absence of a validated social-anxiety outcome and the 'chill session' retreat option.
Virtual reality social skills practice helps autistic children recognize emotions better
A pre-post study with 30 children diagnosed with Asperger Syndrome or PDD-NOS found that 10 sessions of social cognition training in Second Life (a desktop virtual world, not a head-mounted display) produced significant improvements in 3 of 7 measured outcomes: affect recognition, theory of mind (intentionality), and analogical reasoning. Four outcomes - including the Ekman60 emotion recognition task - did not show significant change.
A virtual world gives people with aphasia more opportunities to practice communication
People with aphasia who spent time communicating in a virtual world called EVA Park showed meaningful improvements in functional communication and reported greater confidence in their everyday interactions.
Meta-analysis of 37 RCTs (n=2,991) comparing three technology-assisted interventions for social anxiety disorder: internet-delivered CBT (21 trials), VR exposure therapy (3 trials), and cognitive bias modification (13 trials) - ICBT and VRET both produced large effects vs passive control (g=0.84 and 0.82)
A systematic literature search of Medline, PsycInfo, and Web of Science identified 37 randomized controlled trials of technology-assisted interventions for social anxiety disorder, with total sample n=2,991 participants. Studies were grouped into internet-delivered cognitive behavior therapy (ICBT; 21 trials), virtual reality exposure therapy (VRET; 3 trials), and cognitive bias modification (CBM; 13 trials). Patients undergoing ICBT and VRET showed significantly less SAD symptoms at postassessment than passive control conditions (Hedges' g = 0.84 and 0.82 respectively). Compared to active control conditions, ICBT had a small advantage (g = 0.38); VRET showed comparable effects (p > 0.05). CBM was not more effective than passive control except in laboratory delivery (g = 0.35).
Systematic review of 20 computer-based speech support programs - usefulness supported but none used immersive VR
This systematic review cataloged 20 computer-based speech support programs targeting articulation and phonological differences. All studies supported their general usefulness, though direct comparisons with human-delivered support produced mixed results. None used immersive VR.
VR and CBT show equivalent outcomes for unilateral chronic tinnitus in a therapeutic equivalence RCT
A therapeutic equivalence randomized controlled trial with 148 adults with unilateral or predominantly unilateral chronic subjective tinnitus, comparing auditory-visual 3D VR therapy, cognitive-behavioral therapy (CBT), and a waitlist group. The trial found no significant difference between VR and CBT at 3-month follow-up, supporting the conclusion that VR is at least as effective as CBT for this population.
Three-arm RCT (n=60) of stand-alone VR exposure therapy vs in-vivo exposure vs waiting-list for social anxiety disorder: in-vivo exposure was superior to VRET on multiple secondary outcomes - the opposite pattern to Bouchard 2017
Sixty participants diagnosed with social anxiety disorder were randomly assigned to individual virtual reality exposure therapy (VRET), individual in-vivo exposure therapy (iVET), or a waiting-list control. Both treatments improved social anxiety symptoms, speech duration, perceived stress, and avoidant-personality-disorder beliefs versus waitlist. However, iVET (but NOT VRET) also improved fear of negative evaluation, speech performance, general anxiety, depression, and quality of life. iVET was superior to VRET on social anxiety symptoms at post and follow-up and on avoidant-PD beliefs at follow-up. At follow-up, almost all improvements remained significant for iVET; for VRET only the perceived-stress effect held.

Stuttering and anxiety responses in virtual audiences closely correspond to those in live audiences
A foundational study in ten adults who stutter showing that stuttering frequency during a challenging virtual audience speech correlated at Spearman rho = 0.99 with stuttering during a live audience speech, and that anticipatory apprehension and confidence measured before the virtual condition correlated strongly with the same measures before the live condition (rho = 0.82 and 0.88 respectively). The neutral virtual audience also correlated with the live condition, but less strongly (rho = 0.82 for stuttering frequency).
Can VR elicit SAD-typical distress? In 21 SAD adults + 24 non-anxious controls, VR public-speaking task elicited significant physiological + subjective distress over baseline - but less than the in-vivo task; no SAD-vs-control group differences on physiology
Twenty-one adults with social anxiety disorder (SAD) and 24 non-anxious controls each gave an impromptu speech in front of an in-vivo (live) audience AND in front of a virtual reality audience. Outcomes: heart rate, electrodermal activity, respiratory sinus arrhythmia, and self-reported distress, plus sense of presence ratings. Results: VR significantly increased heart rate, electrodermal activity, RSA, and subjective distress over baseline - but less than the in-vivo task. Participants reported moderate presence in VR, but significantly less than in-vivo. NO significant SAD-vs-control group differences on physiological measures. The study addresses VR's realism-and-validity for SAD clinical work.

Autistic adolescents vs age-matched controls performed comparably on dynamic facial affect recognition in VR, but ASD participants showed lower confidence and different gaze patterns despite matched accuracy
Teenagers with autism spectrum disorder (ASD) and age-matched typically-developing controls performed a dynamic facial affect recognition task within a virtual reality environment. Participants identified the emotion of a facial expression displayed at varied levels of intensity by a computer-generated avatar; the system measured accuracy, confidence ratings, response latency, and stimulus discrimination, plus eye-tracking gaze patterns. Both groups achieved similar accuracy across intensity levels. Despite matched performance, ASD participants endorsed LOWER CONFIDENCE in their responses and showed SUBSTANTIAL VARIATION IN GAZE PATTERNS without underlying perceptual-discrimination deficits. The findings support the hypothesis that autism-related social information processing differs in HOW information is gathered (gaze, confidence) rather than what perceptual discrimination is achieved.
Conceptual design and prototype of an immersive VR CAVE application for training social skills in children with mild autism - early-stage development paper from Cyprus University of Technology
A peer-reviewed conference paper presenting the design and prototype of an immersive VR CAVE-based application for training social skills in children with mild autism. The work is presented as early-stage development - the authors describe the design rationale (drawing on Strickland 1997 and Parsons & Cobb 2011), the CAVE-based immersive visualisation approach, and target use cases for children's social-skill enhancement. Empirical efficacy data on autistic children using the system are not central to this paper - it is a development and conceptual contribution, not a clinical-outcomes study.
Feasibility and acceptability study of virtual environments for treating childhood social anxiety disorder - foundational early-childhood VRET evidence cited as anchor by Delangle 2026 and Moïse-Richard 2021
A feasibility and acceptability study of virtual environments for treating childhood social anxiety disorder, published in the Journal of Clinical Child and Adolescent Psychology special section on Technology and Children's Mental Health. The work examines whether VR exposure environments are tolerable, acceptable, and clinically usable with children with SAD - the developmental phase before the adolescent population studied by Parrish 2016 and before the adult VRET literature anchored by Anderson, Bouchard, and Wallach. Foundational evidence frequently cited as the pediatric-VRET anchor in subsequent stuttering+VR work (Delangle 2026, Moïse-Richard 2021).

VR exposure is as effective as in vivo exposure group therapy for public-speaking-focused social anxiety, with lasting results
In a randomized controlled trial of 97 adults with social anxiety disorder whose primary fear was public speaking, eight sessions of virtual reality exposure were as effective as eight sessions of manualized in vivo exposure delivered in groups. Both active treatments outperformed waitlist on self-report and on a behavioral speech task, and improvements were maintained at 12-month follow-up.

Narrative review - telehealth showed stuttering outcomes equivalent to in-person care; VR framed as a promising next step
This narrative review traced how technology - from telehealth to electronic devices and VR - has reshaped clinical practice for people who stutter. It highlighted telehealth trials showing equivalent outcomes to in-person services and discussed VR as an emerging platform for graduated speaking practice.
Foundational 2011 state-of-the-art review of VR technologies for children on the autism spectrum - the canonical citation in autism+VR work for the decade that followed
A 2011 state-of-the-art review of virtual reality technologies for children on the autism spectrum, published in the European Journal of Special Needs Education by Parsons (Southampton Education School) and Cobb (Human Factors Research Group, University of Nottingham). The paper synthesizes early VR-for-autism work spanning desktop VR, immersive HMDs, and CAVE environments, identifies design and methodological themes, and outlines a research agenda. Frequently cited as the canonical autism-VR review for the decade that followed; surfaces extensively in subsequent autism+VR work (Bekele 2014, Matsentidou 2014, Ip 2018, McCleery 2026).
Master's thesis (n=20): no significant physiological or subjective anxiety differences between adult males who stutter and matched non-stuttering controls during VR speech
A master's thesis: ten adult males who stutter and ten age-matched non-stuttering males each gave two four-minute VR speeches (to a ~30-person virtual audience and to the same empty room). Physiological (GSR, HR, respiration) and subjective (SUDS) measures returned a null between-groups result. The only significant within-group setting effect was on SUDS - both groups rated audience speech as more anxious than empty-room speech.

Video self-modeling improves self-perception after speech restructuring
This trial tested whether adding video self-modeling to standard post-program maintenance would strengthen gains for 89 people who stutter. Objective stuttering frequency did not change, but the video group reported meaningfully lower perceived severity and greater satisfaction at six months.
First-person perspective alone transfers body ownership in VR - synchronous touch not required
A 2×2×2 experiment with 24 male participants showed that first-person perspective (seeing through the virtual body's eyes) alone was sufficient to produce body ownership over a virtual female body - synchronous visuotactile stimulation added little in first-person conditions. The synchronous-touch manipulation only mattered when perspective was third-person. The study established that perspective position is the primary driver of virtual body ownership.
Preliminary 2010 report from Bouchard's group on using virtual humans to alleviate social anxiety - the lineage anchor for the Bouchard 2017 BJP RCT that compared VRET to in-vivo exposure in CBT-integrated treatment of SAD
A preliminary report from Bouchard's Université du Québec en Outaouais group describing early findings on using virtual humans to alleviate social anxiety in a comparative outcome study. Published as a short conference proceedings entry in Studies in Health Technology and Informatics. This is the lineage precursor to the Bouchard et al. 2017 British Journal of Psychiatry three-arm RCT (CBT+VRET vs CBT+in-vivo vs waitlist; in our Hub as bouchard-2017) - documenting the methodological development that led to the later definitive RCT.
